Hybrid tomato variety ‘H2021’

ABSTRACT

Hybrid tomato variety ‘H2021’ is described. The tomato variety is a ground-culture hybrid processing tomato variety suitable for machine harvest and is adaptable to humid climactic conditions of regions such as the Northeastern United States. It is a second early season variety with resistance to  verticillium  wilt race 1,  fusarium  wilt races 1 and 2, root rot nematode, tomato spotted wilt virus, bacterial spot and early blight. ‘H2021’ produces an exceptional set of small, pear shaped red fruit suitable for whole peeling. The superior vine health and extended field storage make it particularly valuable for production regions with high levels of rain that can promote bacterial and fungal diseases and delay field harvest.

FIELD

This disclosure relates to the field of plant breeding. In particular,this disclosure relates to a new variety of tomato, Solanum lycopersicumvariety denominated ‘H2021’.

BACKGROUND

Breeding improved tomato varieties involves providing genetics that givean advantage to the grower, processor, consumer, or other members of thesupply chain. The improvement may be in the form of field performance,disease resistance, factory performance, or a fruit qualitycharacteristic. For a tomato variety to be suitable to be grown forprocessing, the variety must have a concentrated fruit setting andmaturity, firm fruit, and sufficient rot tolerance to allow early fruitto remain rot-free while later fruit continues to develop and ripen.

Most tomato varieties for commercial processing are hybrids resultingfrom a cross pollination of two true-breeding, inbred parents. Throughthe use of true-breeding lines, a hybrid is produced that often displayscharacteristics of each parent, and often demonstrates characteristicsthat are superior to either parent alone, or that allow a hybrid to maskinadequacies of the individual parents.

Processing tomato varieties combining resistance to verticillium wiltrace 1 (Verticillium dahlia), fusarium wilt races 1 and 2 (Fusariumoxysporum pv lycopersici) and root knot nematode (Meloidogyne incognita)are highly desirable in most climates around the world. Moreover, inregions like the Northeastern United States, the industry has seen aconsiderable increase in pressure from bacterial spot (Xanthomonascampestris spp) and early blight (Alternaria solani). Thus, varietieswith resistance are in high demand by both growers and processors toensure a productive crop cycle.

Processing tomato quality parameters differ from those of fruit used inthe fresh market. The processing characteristics are typicallydetermined using a sample of hot-break tomato pulp or juice produced ina consistent manner to those familiar with the art. For example, a fixedmass of tomatoes may be cooked in a microwave oven for several minutesto halt any enzymatic breakdown of the sample, lost water is replaced,and the sample is pulped to remove skins and seed to produce a uniformjuice sample. The juice sample can be analyzed for various qualityparameters important to processing tomato including but not limited togross viscosity measures such as juice Bostwick, soluble solids measuresusing a refractometer (°Brix), measures of acidity and pH, and measuresof color (e.g., a Hunter a/b score). The value of these traits dependson the product that is being commercially produced by the processingfactory. In some instances, a factory will put a higher value on a thickviscosity variety, whereas in other instances, a thin viscosity willmake a superior product and is preferred.

SUMMARY

Provided herein is a new and distinct tomato variety named ‘H2021’ thatproduces high yields of small, uniform elongated (pear shaped) fruit andis best adapted to humid climates, such as the Northeastern UnitedStates. It has also been shown to perform well in humid conditions inEurope, specifically Italy. The variety ‘H2021’ has resistance toverticillium wilt race 1, two known races of fusarium wilt, root knotnematode, tomato spotted wilt virus, bacterial spot and early blight.The fruit of ‘H2021’ are pear shaped, firm, have average color insideand out with an average fruit weight of 55 grams. ‘H2021’ presents anadvantage over industry standard varieties such as ‘H1015’ in that ithas demonstrated resistance to both bacterial spot and tomato spottedwilt virus, which continue to become significant production limitationsin the many humid climates. ‘H2021’ has a pear-shaped fruit; a desirabletrait which makes it suitable as a whole peel variety in many marketslike Italy. Tolerance to fruit rot in ‘H2021’ is very good, allowing foronce-over machine harvesting applications in regions where rain is asignificant factor that can delay harvests and thus require extendedfield holding.

DETAILED DESCRIPTION

Described herein is the new and distinct tomato variety named ‘H2021’that was developed to provide a ground-culture hybrid tomato variety(i.e., not grown on stakes) that is suitable for machine harvest and isadaptable to the climactic conditions of regions like the NortheasternUnited States.

Processing tomato varieties combining resistance to verticillium wiltrace 1 (Verticillium dahlia), fusarium wilt races 1 and 2 (Fusariumoxysporum pv. lycopersici), root knot nematode (Meloidogyne incognita),and tomato spotted wilt virus are highly desirable in many climatesaround the world, including the Northeastern United States and SouthernItaly. Varieties for processing are also valued when they are firm andhave a maturity concentrated enough to allow for machine harvestingprior to the onset of fruit rots. Varieties with tolerance to ripe fruitrots (extended field storage) are also desirable because they areconducive to once-over machine harvesting, particularly in regions whererain can occur during harvest or there are delays in a harvestingschedule.

Tomato plants of ‘H2021’ are resistant to verticillium wilt race 1, twoknown races of fusarium wilt, root knot nematode, tomato spotted wiltvirus, bacterial spot and early blight. Small sprawling plants aremedium green in color with an exceptional overall vine health and adense concentration on small fruit. Fruit of ‘H2021’ are firm and smallin size (55 gram). Maturity until ready for machine harvest isconsidered in the second early class, just a few days later than anindustry standard ‘H1015’ but earlier than ‘H3402’; as with mostvarieties actual days to maturity can vary based upon environmentalconditions.

Stability of Variety ‘H2021’

The variety is uniform and stable within commercially acceptable limits.As is true with other tomato varieties, a small percentage of variantscan occur within commercially acceptable limits for almost anycharacteristic during the course of repeated multiplication. However, novariants were observed during the three years in which the variety wasobserved to be uniform and stable.

Data in Table 1 is based primarily upon trials conducted inCollegeville, Calif. from two replications, non-staked, in a researchplot environment among two checks, ‘H1015’ and ‘H3402’. Data in Tables2, 3, and 4 are based upon observations and laboratory fruit qualitymeasurements made in numerous trials throughout California over a 2-yearperiod, relative to ‘H1015’ and ‘H3402’. Disease resistance andadaptability assessments are based upon DNA markers associated with thedisease resistance when available or numerous observations collected inregions/climates with specific disease pressure, specifically for ripefruit rots, bacterial spot, bacterial canker, early blight, and lateblight, including Ontario, Canada.

Several characteristics can distinguish ‘H2021’ from the similarcommercial variety ‘H1015’, particularly when compared side-by-side intrials. ‘H1015’ has larger and blockier shaped fruit when compared to‘H2021’. Horticulturally, the three most prominent distinctions between‘H2021’ and ‘H1015’ are the resistance to tomato spotted wilt virus,early blight and bacterial spot with ‘H2021’. From a processingstandpoint, ‘H2021’ has a lower serum viscosity and higher juiceBostwick than ‘H1015’ making it more suitable for processors seekingthinner viscosity products. ‘H2021’ has an elongated pear-shaped fruit;which is a significant preference for some humid processing marketswhich prefer the elongated shape for whole-peeled products. Both ‘H2021’and ‘H3402’ are North Eastern US adapted processing varieties with verygood yield. Distinguishing features between these varieties include thedistict foliar health of ‘H2021’ with resistance to bacterial spot andearly blight, and an earlier cropping maturity, with ‘H2021’ coming in afew days earlier than ‘H3402’. These differences are of significanteconomic value to processors.

Further Embodiments

Additional methods provided herein include, without limitation, chasingselfs. Chasing selfs involves identifying inbred plants among tomatoplants that have been grown from hybrid tomato seed. Once the seed isplanted, the inbred plants may be identified and selected due to theirdecreased vigor relative to the hybrid plants that grow from the hybridseed. By locating the inbred plants, isolating them from the rest of theplants, and self-pollinating them (i.e., “chasing selfs”), a breeder canobtain an inbred line that is identical to an inbred parent used toproduce the hybrid. Accordingly, another aspect of the disclosurerelates a method for producing an inbred tomato variety by: plantingseed of the tomato variety ‘H2021’; growing plants from the seed;identifying one or more inbred tomato plants; controlling pollination ina manner which preserves homozygosity of the one or more inbred plants;and harvesting resultant seed from the one or more inbred plants. Thestep of identifying the one or more inbred tomato plants may furtherinclude identifying plants with decreased vigor, i.e., plants thatappear less robust than plants of the tomato variety ‘H2021’. Tomatoplants capable of expressing substantially all of the physiological andmorphological characteristics of the parental inbred lines of tomatovariety ‘H2021’ include tomato plants obtained by chasing selfs fromseed of tomato variety ‘H2021’.

One of ordinary skill in the art will recognize that once a breeder hasobtained inbred tomato plants by chasing selfs from seed of tomatovariety ‘H2021’, the breeder can then produce new inbred plants such asby sib-pollinating, or by crossing one of the identified inbred tomatoplant with a plant of the tomato variety ‘H2021’.

The disclosure further includes introducing one or more desired traitsinto the tomato variety ‘H2021’. For example, the desired trait mayinclude male sterility, male fertility, herbicide resistance, insectresistance, disease resistance, and drought resistance.

The desired trait may be found on a single gene or combination of genes.The desired trait may be a genetic locus that is a dominant or recessiveallele. The genetic locus may be a naturally occurring tomato geneintroduced into the genome of a parent of the variety by backcrossing, anatural or induced mutation, or a transgene introduced through genetictransformation techniques. For a genetic locus introduced throughtransformation, the genetic locus may comprise one or more transgenesintegrated at a single chromosomal location. Accordingly, the disclosureprovides tomato plants or parts thereof that have been transformed withone or more transgenes (i.e., a genetic locus comprising a sequenceintroduced into the genome of a tomato plant by transformation) toprovide a desired trait. In one aspect, the one or more transgenes areoperably linked to at least one regulatory element. In one aspect, thetomato plant or plant part comprising a transgene has all thephysiological and morphological characteristics of tomato variety‘H2021’.

The gene(s) may be introduced to tomato variety ‘H2021’ through avariety of well-known techniques, including for example, molecularbiological, other genetic engineering, or plant breeding techniques,such as recurrent selection, backcrossing, pedigree breeding, molecularmarker (Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), and Simple SequenceRepeats (SSRs) (also referred to as Microsatellites)), enhancedselection, genetic marker enhanced selection, and transformation.Accordingly, tomato seed, plants, and parts thereof produced by suchgenetic engineering or plant breed techniques are also part of thepresent disclosure.

Also provided herein are single locus converted plants and seedsdeveloped by backcrossing wherein essentially all of the morphologicaland physiological characteristics of an inbred are recovered in additionto the characteristics conferred by the single locus transferred intothe inbred via the backcrossing technique. A single locus may compriseone gene, or in the case of transgenic plants, one or more transgenesintegrated into the host genome at a single site (locus). One or morelocus conversion traits may be introduced into a single tomato variety.In one aspect, the tomato plant or tomato plant part comprising a singlelocus conversion has all the physiological and morphologicalcharacteristics of tomato variety ‘H2021’.
